Lifetimes of prolate intruder states in 186Pb and 188Pb and oblate intruder states in 194Po have been determined through recoil distance Doppler-shift lifetime measurements. Deformation parameters of |β2|=0.29(5) and |β2| = 0.17(3) have been extracted from experimental B(E2) values for the prolate and the oblate bands, respectively. The present study addresses the phenomenon of shape coexistence typical for the nuclei near Z=82 and N=104, providing information on configuration mixing of intrinsic structures of the nuclei of interest. The results are compared with the available lifetime data and theoretical results for neutron-deficient Po, Pb, Hg and Pt nuclei. Furthermore, new self-consistent mean-field calculations have been carried out for 194Po.

Majorana parameters of the interacting boson model of nuclear structure and their implication for 0νββ decay

Kleemann, J.; Beck, T.; Friman-Gayer, U.; Pietralla, N.; Werner, V.; Finch, S. W.; Kotila, Jenni; Krishichayan; Löher, B.; Pai, H.; Papst, O.; Tornow, W.; Weinert, M.; Zilges, A. (American Physical Society (APS), 2021)
Effective axial-vector strength within proton-neutron deformed quasiparticle random-phase approximation

Delion, D. S.; Dumitrescu, A.; Suhonen, J. (American Physical Society, 2019)

We use the available experimental Gamow-Teller β− and β+/EC (electron-capture) decay rates between 0+ and 1+ ground states in neighboring even-even and odd-odd nuclei, combined with 2νββ half-lives, to analyze the influence ...

The occurrence of octupolar shapes in the Ba isotopic chain was recently established experimentally up to N = 90 . To further extend the systematics, the evolution of shapes in the most neutron-rich members of the ...
Probing surface quantum flows in deformed pygmy dipole modes

Wang, Kai; Kortelainen, Markus; Pei, J. C. (American Physical Society, 2017)

To explore the nature of collective modes in weakly bound nuclei, we have investigated deformation effects and surface flow patterns of isovector dipole modes in a shape-coexisting nucleus, 40Mg. The calculations were done ...

(Elsevier, 2021)

Prolate-oblate shape coexistence close to the ground state in the strongly-deformed proton-rich A≈120 nuclei is reported for the first time. One of the four reported bands in 119Cs, built on a 11/2− state at 670 keV, ...
